ELASTIC-FLUID TURBINE.

Patented Au. 13, 1912.

Original application filed July 7, 1910, Serial No. 570,879. Divided andthisapplication filed January 23,

1911. Serial No. 604,086.

To all whom iamay concern Be it known that I, \Vrwono DARE, a citizen ofthe United States, residing at Muskegon, in the county of Muskegon andState of Michigan, have invented new and,

engine to which my invention is applied,

taken on the axial plane of the engines rotor, certain parts beingbroken away; Fig.

2 is a sectional view of certain parts taken ..on line ss of Fig. 1;Fig. 3 is a transverse section of certain parts shown in Fig. 2 andtaken on line az-zv thereof, and Fig. t is an under plan view of therotor shaft and parts of the governor connected therewith.

A frame or casing 1 incloscs the operative parts of the turbine engineto which my present invention is applied. The screw plug 2 may beremoved to supply oil. The rotor shaft 3 carries the rotor body 4provided with buckets The elastic fluid (hereinafter referred to assteam) is conducted from its supply by a suitable passage, as thecircular passage (3 in the casing, through an annular opening 7 and apassage 8 into the recess 5) formed in theinner face of the retainingnut 10. The steam then passes through the strainer 11, and throughthe'passage 13 therein, whose lower extremity forms the seat of thevalve it; it is thence discharged by suitable alining passages 15, asshown, into the rotor buckets 5. The steam may also be supplied throughthe opening 45.

A governor to control the valve 14 and regulate the supply of steam tothe buckets, comprises and. operated by the following parts: when thecentrifugal force becomes sullicient to overcome the spring 18, governorbell-crank levers 1S.) pivoted at 20 on the rotor body move the sleeve21 along the rotor.

shaft 3 (which said sleeve encircles) and,

the end of such sleeve being joined to the thrust collar '22 (bearing onthe carbon washer 23 held in the non-rotating collar 24), moves saidcollar 24 axially-the rotor shaft. This movement throws the lever 25,

fulcrumed at 26 and pivoted at 27 to the 001- lar 21, which movement,through the antii'riction roller 28, operates the lever 29'ful- "crumedat 30, and thus closes the valve 14 against the pressure of its spring31 surrounding the valve stem 32, by hearing v against the adjusting nut33, which may be locked in proper adjustment by the jam nut 34. Thepressure of the spring 18, one end of which is fastened to the sleeve 21and the other to theeollar 43, is adjusted by screws 35 threaded in suchcollar and journaled 0n the rotor body, such screws being held fromaccidental turning by their fiat sided heads being held in engagingrecesses 36 in the face of the rotor body. are turned to adjust. thepressure of spring 18, their fiat sided heads are forced, by so turningthe screws, to mount the inclined sides (shown in Fig. 4:) of therecesses 36 at each half turn; the pressure of the spring 18 tending tokeep the heads in the recesses and the turning of the screws raising theheads out of such recesses.

The support or cage 37 of the valve 14: is formed of separate piece fromthe casing or 5 frame of the engine, is conical in shape, shown, and isadapted totightly fit in a correspondingrecess in such casing, in whichit is securely held as by the retaining nut 10,

but may be readily removed to'eflect repairs,

cleaning, etc.- A passage 38 leads from passage 8 to the rear of thevalve 14 for the purpose of adn'iitting steam to balance the pressure ofthe steam on the face of the valve; the area of the cross-section of thepassage 13 and of the cross-section of the annular chamber 46 1s, inorder to efiect a perfect balance, equal. The internal rib 39 inthc'casing serves to confine lubricatihg oil, as shown in the oilchamber 40; the

vapors in the casing chamber, stirred by the motion of the running partsof the engine, take up this oil and thus the governor, etc., areconstantly luln'icated. The screw plug 41 closes an opening in thecasing through which the screws may be adjusted, and

iVhen the screws 35 7 5 the screw plug 42 may be removed to supply -oilto the chamber 40. 'The exhaust pipe is shown at 4A.

This application is division 3 of my original application Serial No.570,87 9, filed July 7, 1910.

My invention may be embodied in varying mechanisms and may be. appliedto other ypes ofelastic fluid engines, and I do not propose to confinemyself to the construction shown and described.

I claim- 1. In a machine of the character described, a valve ca e havinga lifting valve and valve-seat therefor, '21 fluid supply passagecontrolled by the valve, and a fluid passage leading from'the fluidsupply to the inner side of the valve opposite the valve-seat, tobalancelor counteract the pressure of the fluid on the face of thevalve.

2.. In a machine of the character described, a valve support having alifting valve and a seat therefor and a fluid supply assage leading tothe valve seat and contro led by the valve, said support having also afluid passage leading from the source of fluid supply to the inner sideof the valve opposite the valve seat, the area of so much of the face ofthe valve as is pressed by the fluid supplied bythe first-mentionedpassage in the closed position of the valve being equal to the area ofthe rear of the valve pressed by the'fluid supplied by the secondmentioned passage.

3. In a machine of the character described, a conical and removablevalve cage having a fluid strainer with. a fluid passage and radiallyextending straining passages c0m municating therewith.

t. In a machine of the character described having a casing frame and arotatable shaft and a valve for controlling its rotaryspeed, a governorfor said valve comprisin a governor lever centrifugally controlle asecond lever fulcrumed on the casing frame, means intermediate thegovernor lever and the second lever to actuate the latter by the former,and a third lever operating toclose the valve and actuated by the secondlever, said levers and actuating means being cont,ained in the casingframe.

-5. In a machine of the character described having a frame and arotatable shaft and' a valve having a valve stem, for controlling itsrotary speed, said valve and stem having a longitudinal reciprocalmovement, a governor for said valve comprising a governor levercentrifugally controlled, a sleeve encircling the shaft and slidablethereon by the governor lever, a second lever fulcrumed on the frame andhaving a collar pivoted thereto and adapted to be moved longitudinallythe shaft by said sliding movement of the sleeve, and a third leveroperating the valve stem to close the valve and actuated by thesecondlever.

6. In a machine of the character described having a frame and arotatable shaft and a slidable thereon by the overnor lever and.

adapted to move the co lar, and a spring pressing against said movementand whose tension is adjustable by screws carried by the rotor andthreaded in a collar carrying the spring.

.7. In a machine of the character described, having a rotatable shaftand a rotor carried thereby and a valve for controlling its rotary speedand a governor for said valve comprising a governor lever centrifugallycontrolled and connections intermediate the governor lever and the valveto operate the latter by the 'movement of the former, a spring pressingagainst said movement whose tension is adjustable by screws carried bythe rotor and threaded in a collar carrying the spring, and whose headsare held in engaging depressionsagainst accidental movement.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
